Kevin,

For what it's worth, there's a basic eclipse poster and Full Moon map 
available for download on my website   http://www.psychohistorian.org

The "Eclipse!" link is pretty obvious to find; just in case, the direct 
URL is
http://www.psychohistorian.org/index.php?option=com_content&view=article&id=230-partial-lunar-eclipse-august-16&catid=7-eclipses&Itemid=19

Best regards,
Auke
